INTERMEDIATE BUFFERING SYSTEM OF COMMUNICATION PROCESSING SYSTEM

PURPOSE:To improve the throughout of a storage system by providing a common buffer memory between circuit correspondence parts and a file memory. CONSTITUTION:A common buffer memory 5 is provided between circuit correspondence parts 1-1-1-m and a file memory 3. The parts 1-1-1-m contain n-face buffer memories 2-1-2-n respectively and buffer data successively to transfer these data to a terminal connected to the memory 5 or either one of circuits a1-am. The transfer request given from the part 1-1 is immediately accepted by the memory 5 as long as the memory 5 has an idle area. While the queuing occurs at memories 2-1-2-n if the memory 5 is filled fully.
